ElManagerFactory.isElContained incorrect return statement

[eld0727]

Instead of

isElContained: function(findEl){
    return this._el === findEl || $(this._el).has(findEl).length > 0;
}

should be

isElContained: function(findEl){
    return this._el[0] === findEl || $(this._el).has(findEl).length > 0;
}
